GEORGE H. TENOH, OF POTTSVILLE, PENNSYLVANIA.

- WASHER, DRIER, AND SEPARATOR.

SPECIFICATION forming part of Letters latent No. 497,615, dated May 16,1893. Application filed November 18, 1892. Serial No. 452,447. [Nomodel.)

To all whom it may concern.-

Be 1t known that I, GEORGE H. TENOH, of

r Pottsville, in the county of Schuylkill and State of Pennsylvania,have invented a new and Improved Washer, Drier, and Separator, of whichthe following is a full, clear, and exact description. I

My invention relates to improvements in that class of machines which areadapted for use in Washing, drying and separating coal,

culm, pebble phosphates, ore, and similar material, and the objectofmyinvention is to produce a machine which will thoroughly wash, dry andseparate any. of the said materials, which will do the work rapidly andautomatically, which is comparatively cheap, and which is adapted to dothe screening under water so as to avoid creating a dust.

To this end, my invention consists in certain features of constructionand combinations of parts, which will be hereinafter described andclaimed.

Reference is to be had to the accompanying drawings forming a part ofthisspecification, in which similar figures of reference indicatecorresponding parts in all the views. Figure 1 is a broken sideelevation, partly in vertical section, of the entire apparatus. Fig. 2is a cross section on the line 22 in Fig. 1. Fig. 3 is a cross sectionon the line 3-3 in Fig. 1. Fig. 4 is a cross section on theline 44 inFig.1. Fig. 5 is a cross section through one of the scoops, on the line55 in Fig. 3; and Fig. 6 is a cross section through another scoop, onthe line 6-6 in Fig. 2.

The apparatus is provided Wit-h an openended tapering drum 10, which isarranged in a nearly horizontal position and is carried by a shaft 11,the latter being supported in suitable bearings (not shown in the drawings) and the drum is strengthened by spokes 12, the end spokesconnectingwith the drum and shaft, and the middle spokes extending fromthe shaft to the cylindrical screen which is arranged within the drumand which will be described later. On the smaller end preferably, and onthe exterior of the drum 10, is a cog wheel 13, which meshes with a gearwheel 14 on the driving shaft 15, and by this means the drum is rotated.Thesmaller end of the drum is providedwith an inwardlyinclined ringlG,into which extends a supply jchute 17, from which the material to bescreened is delivered intothe drum. The

lower portion of the drum turns in water which is held in an inclinedtank 18, the-tank '18 being supplied by a pipe 19, which is controlledby a valve 20, and which delivers into the-small end of the drum,although it may deliver directly into the tank 18, if desired.

From the lower end of the tank 18, extends a pipe 2l, which iscontrolled by a valve 22,

and through this pipe the dirty water maybe withdrawn.

Arranged longitudinally in the drum 10, is

a cylindrical screen 23, the lower portion of j which is adapted to besubmerged in water, and this screen is carried on the outer ends of the;middle spokes 12, while on its outer tition'is a circular elevatorcomprising a series of nearly radial scoops 26, which extend inward fromthe screen 23 and deliver through the central opening in the'partition25. The scoops 26 are secured to the partition 25 by means of angleirons 27, and the outer edges of the scoops are curved inward, as shownat 28, so as to deliver'through the central opening of the partition 25,and into the tapering supplemental screen or strainer 29. This.

strainer is of circular cross section and at its smaller end is securedto. the partition 25, while its larger end projects outward through theend of the drum and is supported. by spokes 30 carried by the shaft 11.I It will be seen that the rotation of the drum and cylindrical screenwill cause the screened material to be raised by the scoops or buckets26 and delivered into and through the strainer 29,

while the water and any fine material which may be elevated will falloutward and downward through the meshes of the strainer, back i into thedrum. The end wall of the larger end of the drum 10 is of perforated .orscreenin g material, as shown at 31,to admit the water and yet preventsolid matter from passing into the tank, and the middle portion of thepartition 25, is a second series of scoops or buckets 33, which extendfrom the wall of the drum 10 and deliver through the ring 32,

these buckets being adapted to raise the dirt or other fine materialwhich has passed' through the screens 23, and the buckets 33 i are madeof perforated or screening material and have their free edges turnedupward, as;

shown at 33 in Fig.6. Thebuckets or scoops 33 are secured to the wall 31by triangular brackets 33", and their upper ends are curved, as shown at34, so as to deliver into and through the ring 32. The perforations inthe buckets 33 allow the water-lifter with the coal or cnhn to run backinto the tank but are too small for the passage of solid matter.

Beneath the ring 32, and at one end of the tank 18, is a dirt pocket 35,which also extends beneath the strainer 29,and this pocket has aninclined bottom at the lower end of which is a door 36, which mayberaised so as to permit the dirt to be taken from .thepocket.

The coal or other material which is discharged through the strainer 29is delivered into a cylindrical drier and separator 37, this separatorbeing mounted on the shaft 11, and of the usual kind, except that it isinclosed near its front end by asteam jacket 38, which has side flanges39resting on supports 40(see Fig. 4) and the jacket is supplied withsteam supply and exhaust pipes 41 and 42.

It will be seen that by connecting the drier and separator with thewashing and screening mechanism as described, the entire operation ofwashing, screening, drying and separating is carried on continuously andtherefore rapidly.

The operation of the apparatus is as follows: The water is turned on soas to fill the tank 18, and it may be renewed as often as necessary. Thedrum 10 and its containing screen and elevators are set in motion, and

the material to be washed, separated and.

dried is fed into the small end of the drum, from the chute 17. As thedrum revolves the mass of material is caused to gravitate toward thelower end of the screen 23, and the finer particles and dirt will passoutward and downward through the screen and into the lower portion ofthe drum. This screening.

takes place in the water and consequently no dust is raised. When thescreened material reaches the scoops 26, it is lifted by the scoops anddelivered into the strainer 29, and the water and whatever fineparticles may be left drop through the Wall of the strainer, while thescreened material passes onward into the separator 37, where it is driedby the action of steam in the jacket 38,and separated in the usual way.The dirt in the drum 10 gravitates to the lower portion of the drum andis lifted by the scoops 33 and delivered through the ring 32 into thedirt pocket 35, from which it may be taken as often as is necessary.

Having. thus described my invention, I claim as new and desire to secureby Letters Patent 1. The combination with two concentric cylinders, theinner one of which is of less length than the outer and formed ofintersticed or foraminated material, of concentric tubular outlets inthe adjacent ends of the two cylinders and delivering independently,

the drum,a discharge ring or spout arranged around thestrainer, acircular elevatoradapted to lift material from the screen and dischargeit into the strainer, and a second circular elevator arranged at thelarger end of the drum and adapted todischargethe screenings through thecircular ring or spout, sub stantially as described.

3. An apparatus of the characterdescribed, comprising a tapering drumheld to turn insa nearly horizontal position and having its lowerportion submerged in water, a cylindrical screen arranged within thedrum and inclined slightly toward the large end of the drum, a drier andseparator arranged 0pposite the large end of the drum, a circular ringor spout projecting from the larger end of the drum, a strainerextending through the ring and adapted to deliver into the drier andseparator, a series of curved scoops arranged at the opposite end of thescreen and adapted to deliver into the strainer, and a second series ofscoops arranged at the larger end of the drum and adapted to deliverinto and through the circular ring or spout, substantially as described.
